EFI boot regression, SiFive Unmatched

Reported by: kallisti5 Owned by: nobody
Priority: normal Milestone: Unscheduled
Component: System/Boot Loader/EFI Version: R1/beta3
Keywords: Cc:
Blocked By: Blocking:
Platform: riscv64

Description (last modified by kallisti5)

  • hrev55554 - 0f6f5adb - EFI boot fails early
  • hrev55545 - 9b6c4b32 - EFI boot fails early
  • 986199c9 + riscv64 zstd build package - EFI boot fails early
  • hrev55535 - 96b062f1 - EFI Boot works
  • hrev55523 - d171b8b5 - EFI Boot works
  • hrev55481 - 7aa55747 - EFI Boot works

It appears the zstd change to the bootloader was the cause.

Two things happened inbetween hrev55535, hrev55545:

  • A new zstd build-package was uploaded for riscv64
  • A zstd requirement was added to the bootloader

Cause is one of these:

  • 9b6c4b320fe82a94ec4bf7b860090a90b3c1eb71 - add zstd to build-packages
    • Maybe something about this zstd is breaking the bootloader?

Resolution: → fixed
Status: new → closed

this one was solved via hrev55619

zstd included weak symbols resulting in undef zstd calls in the efi bootloader.
